The word that describes the location of the gene for antenna length on chromosome #2 of the fruit fly is called locus. In the DNA of other fruit flies, the gene will be found at the exact same locus.
Antenna is the sensory organ present on the head of many insects. They are present in a pair. The antennae can be sensitive to touch, smell or any other senses. Due to their ability to sense or feel, they are also called feelers.
Locus is defined as the location or the physical place on the chromosome where a gene is present. The word locus is used to define the address of any particular gene. The loci are fixed for a gene in all the chromosomes of any organism.

2. 0%
Explanation:
A) Given Curly hair is dominant over straight hair.
Let the allele representing straight hair be "c"
and the allele representing curly hair be "C"
a) a woman heterozygous for hair curl, a man heterozygous for hair curl will
Cc * Cc
CC, Cc, Cc, cc
75 % curly and 25 % straight hairs
Hence, option A is correct
B) TT * Tt
When TT or Tt is crossed with tt, not all offspring will be tall
In order that all offspring are tall , the probability that both the parents must be homozygous recessive is 0%
